12 - Atomic Absorption spectrometer

With double-beam system for maximum stability. It uses durable quartz-coated, reflecting optics for optimum energy throughput and a high-dispersion monochromator together with a high-performance photomultiplier for solid analytical performance.A bright two-line alphanumeric display prompts the user through the initial instrument setup in easily understood terms. It also displays analytical results and trouble-shooting messages. Flame, furnace and flow injection operation modes can be selected via pushbuttons. The build-in microprocessor provides results in absorbance, emission or concentration and allows the user to select the integration time, the scale expansion, multiple calibration standards and some basic statistics.The build-in gas control system combines ease of operation with a full complement of safety features and interlocks. A large sample compartment accommodates either the standard dual option burner system, an HGA graphite furnace or a mercury/hydride system.Specifications: Dimensions pprox.: 720x550x390mm; Weight: 55Kg; Power: 100/120/220/240 Volt, 50/60 Hz, 150 Watt; Spectrometer: 0.267 Littrow monochromator, 1.6 nm/mm linear dispersion.
